Answer Key to Exercises 

Each lesson ends with an exercise. Each exercise contains about 8-12 questions. The answers to the questions can be found at the back of the book.


In today's day and age, I feel this book/workbook is essential for students. Over the past few years, we have been bombarded with propaganda, mob mentality, fear, and coercion. Our children need to understand how these tactics are used against them every day. It is important that they see how things are presented and it is even more important for them to stand up and make their own educated decisions. 

When I was reading this book, I was immediately brought back to a question my mom would ask when we wanted to do what everyone else was doing, "If everyone else jumped off a bridge, would you?"
Of course not, I wasn't crazy or stupid. When she'd asked that, it made me stop and think (at least most of the time). I still wanted the designer jeans!
The Fallacy Detective is a great introduction to logical fallacies and bad reasoning. It's a great book to help students begin to learn how to apply critical thinking skills. I do believe and more in-depth logic thinking course is needed for older students in high school or college. We may not have agreed with everything presented in the book, but The Fallacy Detective was a fun, engaging start to learning about logic.
